Abstract

I cis or trans-EAn Cn hexanone yields alkenals in good However, for the photochemistry of large-ring unsubstituted cycloalkanones, the dominant primary process if y-hydrogen abstraction, which affords cyclobutanol derivative^,^ al-though 2-methyl-substituted cyclododecanones undergo both a-cleavage and y-hydrogen abstra~ tion."~ We report the photochemistry of large-ring 2-phenylcycl~ alkanones~(11-to 15-membered) that produce ...
